Description

Cooler

Technical field

The utility model relates to a kind of cooling device, especially relates to a kind of cooler that mould after processing or product are cooled off.

Background technology

In the production process of cast or injecting products, need carry out the product in the hot setting shaper usually to the mould of pouring into a mould, in mould, take out the product that cast cured explosive is finalized the design again; Or to the die material of injection formed and products thereof the processing that cools, to reach the effect that realizes cooling, typing.And cooling after the casting mold high-temperature shaping is solidified handled usually, generally adopt simple cooler bin or cooling tank, adopt single unit to place operations such as cooling, taking-up, not only labour intensity man-hour big, that take is many, production efficiency is low, and confusion reigned situation in the process of cooling easily in the mould production of different model at the same time, be unfavorable for controllable quality, also be easy to generate more mould holding time; And in when typing of cooling, cause because of the water temperature of cooling water changes that cooling is inhomogeneous to cast or injecting products, the shrinkage factor uniformity is poor during cooling, typing is unstable; And then cause in the cooled injection mold product phenomenons such as weld bond, speckle, surface smoothness are low, poor mechanical property, percent defective height to occur.

The day for announcing is that the granted patent ZL200520081390.6 on March 8th, 2006 discloses a kind of injecting products cooling conveying device, be included in the bosh of the front lower place setting of many injection machines that are the in-line arrangement, the end of bosh is connected to aqua storage tank, the spray header that is communicated with the cooling water outlet pipe of injection machine is installed in the bosh inner chamber, be equipped with on the spray header and be a plurality of spray heads that in-line is arranged, the water spraying direction of each spray head is towards the end of bosh, the top of bosh is communicated with the cooling water outlet pipe of injection machine, and cross-over connection has conveyer between aqua storage tank and product container.This injecting products cooling conveying device becomes the one man operation multimachine by original single single-set operation on the one hand, and production efficiency increases substantially; Automatically fall into behind the machine under the injecting products on the other hand in the bosh, cool off by last spray and following current double action, even water temperature, good cooling results, product is indeformable, and cooling shaping is stable, has improved product quality.But this device is to consider to increase the spray header effect again on original bosh basis basically, still need to use a lot of boshes, same to a certain extent the existence operated inconvenience, the focus utilization that is unfavorable for the equipment of cooling, and the cooling water inflow of single tank and water temperature all may exist phenomenons such as not enough and easy rising, and then cause having influence on inhomogeneous, poor, the unsettled situation generation of setting of shrinkage factor uniformity when cooling off of cooling, be unfavorable for the raising of percent defective.

The utility model content

The utility model has now in the production process of cast or injecting products for solving, processing existence operation is inconvenient, labour intensity is high in that die material and products thereof is cooled, the man-hour that takies is many, production efficiency is low, and have in the cooling that cooling is inhomogeneous, the shrinkage factor uniformity is poor during cooling, typing is unstable, and then present situation such as weld bond, speckle, surface smoothness are low, poor mechanical property, percent defective height appears easily and provide a kind of easy to operate, labour intensity is low, production efficiency is high, lowering temperature uniform, setting good stability, cooler that percent defective is low.

The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be: a kind of cooler, comprise frame, rack-mounted motor, it is characterized in that: the fuselage of cooler adopts annular shape, frame is provided with annular delivery track, delivery track is provided with row's delivery tray, and delivery track comprises to be carried straight way and be connected the downward-sloping conveying ramp and the annular feed track at two ends with carrying straight way; Carry the lower end of ramp to connect cooling bath bottom feed track, be connected with acclivitous conveying ramp from cooling bath bottom feed track again, be connected with carrying straight way then, constitute the delivery track of whole cooler, seal the peripheral body portion of cooling bath that body forms cooler inside and outside the cooling bath bottom feed track that conveying ramp and slope sink; Be connected with cooling liquid in cooling bath, delivery track is by motor sprocket 21 transmission links on delivery track driving member and the motor, and motor is connected with automatic control box.Motor sprocket on the driven by motor motor arrives drive sprocket by chain drive, drives sprocket wheel transmission piece, and then drives delivery track by setting the rotation direction rotation, makes whole cooling machine run; Adopt mechanical sucker hand or manually be with heat protective gloves, the die material that injection moulding is come out is put on the delivery tray of carrying straight way, work along with chain drive and drive sprocket, placement is fixed on die material on the delivery tray of carrying in the straight way along with delivery track is carried and said through carrying ramp and entering the cooling bath bottom, enter carry ramp in along with the cooling fluid that also progresses into cooling bath in, cooling fluid can adopt recirculated cooling water or other specific cooling fluid, and die material can be lowered the temperature fully in cooling bath, be cooled off; Simultaneously the speed of service of delivery track can be regulated by the flexible setting of automatic control box according to the actual mould product, the speed of service and the cool time of control die material in cooling bath, satisfies the production needs of different situations; After die material passes through cooling of cooling bath, by carrying ramp to rise on the conveying straight way of level, cooled mould product can be unloaded again, be placed on the place of appointment, finish the processing that cools die material; The delivery track cycle operation, simple, convenient, can realize with minimum personnel's control operation processing that cools of die material in batches, the production efficiency height, simultaneously can better satisfy the uniformity that reaches lowering temperature uniform, shrinkage factor, qualitative stable effect, enhance productivity to a greater extent and quantize the production degree.The more production management of rational and orderly is conveniently carried out in mould, the product that can carry out different model on a cooler line simultaneously processing that cools, and confusion can not take place.

As preferably, described cooling bath adopts annular cooling bath, and annular cooling bath is located at the annular end place of annular shape cooler.Make full use of the annular end place of cooler, as the place that cools, the straight way of cooler partly can be used as other production operation place and uses, and has made full use of space, production place.
